SNOOK, this is the website/froum issues forum.
You need the Johnson/Evinrude repair forum where I will move it to now.

Try running with the cover off to be sure that you are not getting exhaust in the engine compartment.​

When it begins to cut off, assure that you can touch the tops of the cylinder heads for three seconds or more as you may be overheating.​

The high speed orifice in your carburetor may be clogged.

Check your ignition coils for cracks, breaks, melting and color fade.​
